comprises a frame with rods across the same, and a set of polygonal blocks on each rods are parallel and are spaced apart equal distances. An equal 'number of similar polygonal blocks 8 are loosely mounted or placed on each rod, the blocks having holes at the center, for that purpose. The blocks shown are octagonal, but may be any other polygon. Each of the side faces of the blocks is distinctively marked, as with a letter, Word, picture, number, abbreviation or the like, and also preferably with a distinctive color, sothat the device will serve to teach colors, as well as words and symbols.
